INVALIDS TABLE.

v Specification of Letters Patent.

Patented Oct. 1909.

Apmication mea may 1s, 1909. serial No. 496,701.

To all 'whom it may concerm' l Be it known that We, FERNANDO A. SMITH' jand DANIEL L. OBRIEN, citizens of the United States, residing at SanFrancisco, in the county of San Francisco and State of California, haveinvented new and useful Improvements in Invalids Tables, of which thefollowing is a specification.

The present invention relates to improvebed.

The object of the invention is to provide a table of this characterwhich can be attached directly to the bed, can be constructed at acomparatively small cost, and can be easily and 'quickly adjusted as toits height, its -lateral position, and the magnitude and direction ofits inclination.

While the device is of particular utility for invalids, it is also ofvalue as a bookrest to be attached to the arm of a chair.

In the accompanying drawing, Figure 1 is use; Fig. 2 is a verticalsection on the line 2-2 of Fig. 1; Fig. 3 is an enlarged horizontalsection on the line 3 3 of Fig. 1. j

Referring to the drawing, 1 indicates a clamp, having a top or middleplate 2, an inner Harige or wall 3, and an outer flange or Wall 4.Through the' latter iange are screwed thumb screws 5, having roundedheads 6, entering sockets in shoes 7, which are adapted to fit againstthe side of the article of furniture 8, such as the arm of a chair orthe side of a bedstead', to Which the device is to be attached. Saidclamp is also formed on the outer side With a central extension 9,having a vertical aperture or slidevvay 10, through which can slide apost 11. Said post is formed With a series of annular grooves 12, andlin said4 clamp is formed a socket 13 Within which is received a bolt 14connected at its inner'end t0 a coiled spring 15 securedk Within saidsocket. Said spring projects said bolt a short distance into theslideWay 10, so that its outer end can engage, in turn, the grooves 12in the post, as the latter is raised `or lowered for the purpose ofadjustment; but, since said outer end is rounded, the bolt readily slipsout of each groove as the post is moved vertically. The person adjustingthe device is informed by the sense of touch, when the bolt engages anyone of the grooves, and he l can then, if desired, secure the post inthat position of extension by screwing ina thumb screw 16, the roundedinner end of which can enter said groove. The screw 16 does not,however, prevent the post from being turned freely on its axis.

The upper end of the post is bent a't right angles to form an arm 17,and the surface of the arm is grooved longitudinally, as shown at 18. Onsaid arm can slide a sleeve 19 secured' to the under side of a table 20,and a thumb screw 21 is screwed through a boss on said sleeve and isadapted toenter any one of the grooves 18' in the arm and thereby retainthe table in the corresponding position either horizontal or inclined.This sleeve 19, like the clamp 1, is provided with a spring actuatedbolt 22 adapted to enter any one of a series of longitudinal grooves 23in the arm corresponding-with the several positions of angularadjustment of the table on the arm. It will be seen that, by thisarrangement, any desired adjustment may be easily and quickly obtainedof the table, as to height, lateral position over the bed or chair,inclination to the horizontal, and direction of slope.

1. AA device of the character described, comprising a clamp having avertical bearing, a post in said bearing having a series of annulargrooves and bent at the top to forni a horizontal arm, a bolt in asocket` through said clamp and also adapted to enter one of saidgrooves, and a table secured upon `the upper end f said arm, substantially as described.

2. A device of the character described, comprising a clamp having avertical bearing, a post in said bearing having ya series of annular=grooves and bent at the top to form a horizontal arm, said arm beinglongitudinally grooved, a bolt in a socket in said clamp and having a4rounded outer end, a
